Product catalog summary
Trench Adapter Construction
The trench adapter features a plastic cap for sealing, a 2-inch square wrench nut, reinforced guides, a self-centering alignment ring, an extension stem stop, a coupling gland, an O-ring, a grit and stem washer, and a valve box top made of ductile iron. The lid is secured with a stainless steel bolt and accommodates standard 2-inch gate valve wrench nuts.
Features and Benefits
The trench adapter includes a self-centering alignment ring for easy installation and alignment, adjustable trench depths from 3 to 20 feet, and eliminates the need for field-cut extension stems. It ensures the operating nut is accessible at ground level, preventing issues with debris and misalignment. The extension stem is tested to withstand up to 1000 ft-lb of torque.
Specifications
The trench adapter is a complete unit with a valve box, extension stem, centering ring, debris washer, and lockable lid. It is adjustable for various trench depths without cutting. The stem assembly is telescopic, made of galvanized steel, and designed to prevent disengagement at full extension.
Dimensions and Model Numbers
Model numbers correspond to specific trench depths and valve sizes, with detailed tables provided for selection. The assembly weights range from 29 to 127 lbs depending on the model.
Retrofit Valve Box Insert
The retrofit insert upgrades existing valve boxes with features of the trench adapter, including a self-adjusting extension stem and grit washer. It ensures the operating nut is accessible at ground level and prevents debris entry. The insert is adaptable to fit standard valve boxes and is tested for durability.
